Part Number: NC-MXT-BR-12

These are the finest machined shotshell tube extensions currently available. Each tube has a unique swirl style barrel nut adding a distinct touch while also providing a quick and sure grip.

Currently available in +2, +3, +4, +5, +6, +7, +8 and +9 configurations for the Beretta Extrema / Extrema 2 / A400 and Benelli Nova / Super Nova shotguns. Shell capacity is defined by Nordic as the shell increase above and beyond the standard capacity provided by the fixed magazine tube (tube inside the forearm). If your shotgun currently has a short tube extension, the round capacity of that extension would be lost as it is removed and replaced. Magazine tube length is the length of the tube and nut.

To use a stock Nova as an example, if it holds 3 shells in the fixed factory tube, and a +4 Nordic tube is installed, you will have a 8 shell capacity, 7 in the tube and 1 in the chamber.

The chart below lists some important information about the Nordic Components tube extensions. If you have an 18 inch barrel, you probably would not select a +4 or greater tube extension, as the extension would stick out quite a bit further than the end of your barrel. That is a perfectly viable option for shotgun use, it is your personal choice as to whether tube extends past the barrel. Please decide before you buy as to whether it is acceptable to you for a tube to extend past the barrel.

Directions for selecting the proper tube extension length:

Using the tube overall length provided above, please determine the complete installed length of your shotguns fixed tube and the tube extension. Once this is done, it should be apparent that some tubes will extend past the end of your barrel when installed. That is a perfectly viable option for shotgun use, it is your personal choice as to whether tube extends past the barrel. Please decide before you buy as to whether it is acceptable to you for a tube to extend past the barrel. Otherwise, the extension which comes closest to the end of your barrel is the proper tube length to select.

An extended spring is included with the magazine extension tube.
